Luís Gil, a specialist on cork and one of our invited authors, has just appeared on RTP2 – Portuguese TV. The show is in Portuguese (sorry, no subtitles). Cork is a sustainable natural material, its growing uses very diverse – sealing wine bottles, protecting the precious nectar, as floor coverings, space and aeronautics and, increasingly in fashion accessories. Portugal is the largest world producer, accounting for 1/2 of total production and exporting 2/3 of that.
